"CHEMIST 212 C Securebckbd CHEMISTRY 212 1. Why is it necessary to standardize an NaOH solution? Look up the molecular weight for potassium hydrogen phthalate (KHP) and determine the number moles of KHP in 1.85 g of KHP. 2. . An NaOH solution of unknown concentration is used to titrate 1.85 g of KHP. The initial reading of the burette is: V-8.35 mL. The student titrates the sample to the point where the solution has just turned pink. The final burette reading gives V-19.40 mL Calculate the concentration of the NaOH solution. If the NaOH solution from question 4 is used to titrate 25 mL of 0.682 M HCI, how much NaOH will be required? 4. O Type here to search 30203
